Technical Analysis

VPN clients are commonly found on laptops for remote office workers, This is a local priv esc on all Aviatrix VPN Clients. As it is local it would need either a malicious user or an attacker with User level access looking to escalate.

Due to file permissions on scripts that are executed to start and stop the VPN client, it is trivial to inject arbitrary OS commands that can be used to escalate privs.
